A shooting at a shopping centre in Indianapolis on 28 October left three wounded, police said. According to an Indianapolis Metropolitan Police spokesman, the shooting at Washington Square Mall happened at around 6.30pm when the suspected gunman encountered a man he knew and began shooting.

"This was a targeted individual. They had words," Deputy Chief Brian Mahone said during a press conference. "This is not a random act." Mahone told reporters that the suspect fled the shopping mall and is not in custody.

Indianapolis Police Sergeant Kendale Adams told Reuters that the three victims — a woman and two men — were able to run through the Target store connected to the shopping centre following the incident. They were taken to nearby hospitals. "None of the injuries are believed to be life-threatening," Adams said.

However, according to CBS News, one of the men injured was taken to Methodist Hospital in critical condition. The other man and the woman were taken to Eskenazi Health with non life-threatening injuries. USA Today reported that details surrounding the shooting have been limited. Police have not revealed how many shots were fired or released a description of the suspect.
